1 Messages of Enterprise Cluster NAS Huawei OceanStor

2 Messages of Enterprise Cluster NAS 1. High performance and high reliability, addressing bid data challenges High performance: In the SPEC benchmark test, the outperforms counterparts in NFS/CIFS performance, meeting customer requirements. Benefits: The cluster scale-out architecture meets the high concurrency and high bandwidth requirements of highperformance computing and media assets. Differentiators: The multi-node active-active cluster technology is employed. All nodes in a cluster work jointly to enable concurrent data access. All nodes are allowed to access the same storage space simultaneously. The performance tested in SPEC sfs2008 reaches 3,063,530 OPS, which is twice that of the runner-up's performance. Highly reliable architecture design: Load balancing is available. There are no single points of failure. Benefits: The system architecture is fully redundant without a single point of failure, ensuring business continuity. Differentiators: Engine nodes have the load balancing function. Accesses to hotspot data are evenly distributed to all of the nodes, improving hotspot access efficiency. All components are redundant, preventing single points of failure. such as data coffer and file system mirroring further improve system reliability. The cluster scale-out architecture is based on the multi-node active-active mode. The performance is improved linearly as engine nodes and disk arrays increase. The hardware system is fully redundant, ensuring high system reliability. 1

3 Messages of Enterprise Cluster NAS PB of flexible space and over one hundred billion files, supporting rapid business growth High scalability: The storage capacity and NAS engine nodes can be expanded flexibly. Benefits: The performance and capacity of the can be dynamically expanded in online mode based on customer business developments. Differentiators: Up to 24 engine nodes are scalable. The system performance is improved linearly as engine nodes increase. The storage capacity is scalable up to 15 PB. Mass processing capability: A file system can process up to one billion files. Benefits: Up to 256 file systems can be configured based on specific services and applications. Each file system can process up to one billion files, easily handling Internet applications that feature massive small-sized files. Differentiators: A file system of up to 256 TB is supported. Each file system supports up to 1 billion files. A flexible and scalable architecture design is adopted, which supports an initial configuration of two engine nodes and is scalable up to 24 engine nodes. Multiple disk arrays are supported. As a cluster is expanded, the storage capacity is increased and the performance is improved linearly. Multiple file systems are supported, facilitating service planning. A single file system has a sufficient capability to handle applications of massive small-sized files. 2

Benefits: The DST function enables files to be migrated between different storage media based on the predefined policies. Data migration is transparent to applications. Differentiators: Based on file access frequency, the time policy better suits users' habits. High-speed and low-speed disks are configured based on the ratio of hotspot data to non-hotspot data. Compared with the configuration of all highspeed disks, the TCO is reduced by 60%, cutting enterprises' costs. The file system mirroring function improves data reliability. Benefits: A file system mirror can be configured on the same storage system to store multiple copies of data, improving online data reliability. Differentiators: The file system mirroring function, together with multiple disk arrays, implements double data protection. Data can be stored on different disk arrays, providing logical and physical data protection. File-based DST policies better suit actual application environments. In addition, the configuration of high-speed and low-speed storage media decreases investments. The file system mirroring function is based on the 's unique hardware architecture. Logical and physical data protection is implemented using the cluster software. 3

5 Messages of Enterprise Cluster NAS 4. Smart integration, simplifying the infrastructure Unified protocols: Multiple protocols are supported, meeting customers' needs for multiple service applications. Benefits: Multiple protocols are supported. One system supports both NAS and SAN applications. Differentiators: Unified storage incorporates SAN and NAS storage protocols. One storage system can store both structured and unstructured data. Protocols, such as iscsi, FC, NFS, CIFS, HTTP, and FTP, are supported. Unified management: The same management software manages both NAS and SAN devices. Benefits: Network management is simplified, facilitating administrators' system configurations and management. Differentiators: A user-friendly GUI is provided to manage file data and block data in a unified manner. The wizarddriven configuration mode assists users in completing various configurations. One system supports both SAN and NAS applications, cutting the initial investment. File-level and block-level data protection is provided, including snapshot, mirror, and remote replication. A unified network management interface is provided, simplifying infrastructure management. 4
